Title: Channel sounder measuring mobile radio channels - uses special, optimum test signal with several spectral lines having slight crest factor
Inventor: BAEHR GERHARD DIPL ING
IPC: H04B17/00
Filed: 1992-10-02
Abstract: The system comprises a transmitter propagating a periodical, analog test signal, and a receiver, in which the time variable, complex reply word of a mobile radio channel is determined in real time. A special, optimum, complex test signal is used, which has several spectral lines, and whose complex envelope has a slightest possible crest factor in the time range. The receiver contains an optimum, true expectancy estimator for channel measuring, in which a calibration is carried out for determining the measuring frequency, while the transmitter and receiver are directly coupled. The estimator also determines the pulse response of the band bound mobile radio channel according to a division of the reception spectrum by the measuring frequency. ADVANTAGE - No correlation secondary crest, while giving precise measuring of transmission function within measuring band width.

Title: Antidazzle device for motor vehicles
Inventor: FLECK OSKAR
IPC: B60J3/02
Filed: 1993-09-25
Abstract: The invention relates to a device (1) for protection against dazzling by light with a spindle (4) which is arranged by way of a fastening device (3) on a frame pillar (2) of a motor vehicle and by means of which an antidazzle strip (5) can be swivelled to the driver's or passenger's eye-level.

Patent DE-4405206-A1 (DE)
Inventor: NIEMEYER LUTZ DR
IPC: H01H33/14
Filed: 1994-02-18
Abstract: The device for switching electric current comprises a compressed gas switch, at least one vacuum switch (14) and two terminals (2, 3). In this switching device, a first consumable contact (10) of the compressed gas switch is electrically connected to a fixed electrode (15) of the vacuum switch (14), a second consumable contact (7) of the compressed gas switch is connected to a first (2) of the two terminals (2, 3) and a movable electrode (16) of the vacuum switch (14) is connected to a second (3) of the two terminals (2, 3) to form a quenching circuit. The two electrodes (15, 16) of the vacuum switch (14) can be separated without the use of the drive (5) and a contact pressure is applied to them which prevents the electrodes (15, 16) from breaking below a threshold value of the current to be switched off. On switch-off, the current to be interrupted is switched over from a rated current circuit containing two rated current contacts (8, 11) of the compressed gas switch to the parallel quenching circuit. The vacuum switch (14) now in the quenching circuit breaks only if the current to be switched off exceeds the aforementioned threshold. As the vacuum switch (14) does not conduct the rated current and, unlike the compressed gas switch, is involved only in a few break operations, it can be of substantially lighter construction than a vacuum switch carrying the rated current and is actuated in every switching operation.
